摘　　要：对二段式圆柱型ＨＡ－Ｔｉ复合种植体上部结构修复后３月以上，经严格临床追踪观察的１６２例计２３６件修复体临床资料进行总结分析。结果表明：金属－烤瓷、金属－塑料作材料的各种类型的修复体临床效果均较满意，而以塑料牙作材料的各类修复体临床效果均差。作者认为金属－烤瓷、金属－塑料作为种植义齿上部结构修复材料较合适。This study was to evaluate the feasibility of plastic crown restoration supported by osseointegrated implants. The following conclusions were drawn from this study: plastic crown gave better biomechanical consideration than porcelain fused to metal (PFM) crown in osseointegrated prostheses, but plastic crown gave worse wearability, tensile strength, compression strength and flexuaral strength than PFM crown. After restoration the disadvantages of the plastic crown were beyond the clinical acceptable range. It showed plastic crown designed dental prothetic implantation was unfeasible.
